Abstract
IN A MAGNETIC DISK GLASS SUBSTRATE MANUFACTURING METHOD, A MAIN SURFACE (11) OF A GLASS SUBSTRATE (1) IS POLISHED USING A POLISHING LIQUID CONTAINING COLLOIDAL SILICA ABRASIVE PARTICLES AS POLISHING ABRASIVE PARTICLES AND A SURFACE PLATE WITH A POLISHING PAD (7), THEN THE GLASS SUBSTRATE (1) IS BROUGHT INTO CONTACT WITH A LIQUID CONTAINING A COAGULANT SO THAT THE COLLOIDAL SILICA ABRASIVE PARTICLES ARE COAGULATED, AND THEN THE COLLOIDAL SILICA ABRASIVE PARTICLES COAGULATED ARE REMOVED.
